Interesting. Does the Airbus give you a alert should one keep climbing with Gear Down?
Well, if it was not for the associated buffeting, I wonder how long they would go on for, and at what height/speed serious damage starts to occur.
I don't think that's the big issue here. Consequences of playing with thrust at low level, 40kt excessive rotation, below minimum pitch angle could get a little hairy...
What happened
On 29 September 2018, a Jetstar Airways Airbus A320 aircraft, registered VH-VFK, was operating a scheduled passenger flight from Sydney, New South Wales to Melbourne, Victoria. While preparing for the flight and having difficulties with the electronic system used for calculating take-off performance figures, the flight crew reverted to the back-up procedure of manual calculations.
Shortly after take-off, the maximum flap extended speed was exceeded. As the aircraft climbed through 2,800 ft, the flight crew retracted the landing gear after realising it was still extended, resulting in a landing gear retraction overspeed.
Findings
These findings should not be read as apportioning blame or liability to any particular organisation or individual.
- The flight crew did not follow standard operating procedures to verify and update Flysmart database during sign on for the day.
- When using manual calculations to obtain performance speeds, the flight crew made an error which was not detected by independent validation. This resulted in a calculated rotation speed based on an aircraft weight significantly heavier than the actual take-off weight.
- The rotation rate commanded by the pilot flying was too low to prevent a flap overspeed, given the incorrect performance speeds and use of maximum take-off thrust.
- In an attempt to manage the airspeed, the pilot flying reduced the thrust from the take-off setting, rather than increasing the pitch, but the aircraft was below the safe altitude above the ground to do so.
- The landing gear was not retracted at the normal phase of the take-off. When the flight crew identified that the landing gear was still extended, they retracted it immediately, even though the aircraft was above the maximum landing gear retraction speed.
